Abstract

Multiple shoot induction was studied in upland cotton cv. NIAB-999. Cotyledonary nodes obtained from
aseptically raised seedling were cultured on modified Murashige and Skoog medium (MS) supplemented
with different doses of Kinetin. Cotyledonary nodes produced maximum number of shoots (3.43 shoots/
explant) when cultured on MS medium supplemented with 0.25 mgl-1 Kinetin. Highest percentage (93.3 %) of
root development and root length (5.85 cm) was obtained when shoots were cultured on MS medium
supplemented with 0.5 mgl-1 napthalene acetic acid (NAA) and 0.1 mgl-1 Kinetin.
